Enerpac Underground Intensifier Pump

After working with Enerpac, we now have a custom-built Intensifier Pump to speed up the bolt tensioning process in underground mining and tunnelling.

Engineered for Potentially Explosive Atmospheres —  No Exposed Aluminium Components  —  Safe for Underground Use

The CMP Point of Difference

All exposed aluminium components have been replaced with alternative materials. The traditional foot pedal operation has been replaced with a simple directional control lever on the manual pumps and a pendant control for the pendant pump. Operation is easily controlled from the palm of your hand.
